Abstract:

The self-developed heat flow coolness tester was adopted to test the transient heat flux density maximum and the quilibrium heat flux density of fifty-seven fabrics. Using the above test values, the contact feeling of the fabric was evaluated from both subjective and objective aspects. For objective evaluation, the cooling evaluation index of fabrics was divided into five categories based on They were marked as A,B,C,D and E, the coolness was weakened in turn. The fuzzy comprehensive evaluation method was used to classify the transient and steady heat flux values obtained by the test, and obtained the range of transient and steady heat flux values corresponding to different coolness levels. For subjective evaluation, the tester directly touched the fabric to evaluate and analyzed the cool feeling of the fabric subjectively, and obtained the coolness level of the fabric. Subjective and objective evaluation of fabrics has a strong consistency in the contact cooling results, the cooling grade of textile fabrics is accurately divided, which can promote the specification of the cool textile market.

Key words: cool feeling of fabric, coolness level, fuzzy comprehensive evaluation method, membership function, subjective evaluation
